"According to its banner, the version of PHP 5.5.x in use on the remote
web server is a version prior to 5.5.15. It is, therefore, affected by
the following vulnerabilities :

  - A use-after-free error exists in the file
    'ext/spl/spl_dllist.c' related to the Standard PHP
    Library (SPL). Using a specially crafted iterator,
    an attacker could cause a denial of service condition
    or other unspecified impacts. (CVE-2014-4670)

  - A use-after-free error exists in the file
    'ext/spl/spl_array.c' related to the Standard PHP
    Library (SPL). This could allow an attacker, using
    'ArrayObjects' or 'ArrayIterator', to cause a denial
    of service condition or other unspecified impacts.
    (CVE-2014-4698)

  - The function 'sapi_cli_server_send_headers' in the file
    'sapi/cli/php_cli_server.c' contains an error that does
    not properly handle an empty 'header' parameter and
    could allow denial of service attacks. Note that this
    issue affects only the built-in command line development
    server.

Note that Nessus has not attempted to exploit these issues, but has
instead relied only on the application's self-reported version number.");
